Keurig Descale Light – How To Turn It Off

Everyone wants to wake up to a refreshing cup of coffee in the morning. But, coffee machines are unpredictable and sometimes can break. One of the most popular coffee machines in the world right now is Keurig, and they have a common problem that we will be going over today. The problem is that the Keurig descale light stays on.

If you are having this problem, you have come to the right place, as through this article, we’ll be going over how to fix this problem.

how to fix keurig descale light

First of all, we need to know why this light turns on in the first place.

Why Is The Descale Light On?

The descale light is a common feature in many coffee makers, and basically, when the descale light turns on, it is signaling that your coffee maker actually needs cleaning.

The light can come on when particles of calcium or dirt collect on the inner parts of the machine, clogging the machine up. Sometimes, the machine can stop working when this happens.

Another reason the descale light can come on is because if you use refillable K-cups, at times, you may pack your cup too tightly, which can restrict the water flow inside the machine. This can lead to a descaling light actually coming on.

How To Fix It?

You should descale (clean) your Keurig around every three months; if the time for a clean has come, let us help you out.

Here is an in-depth youtube guide on how to descale your Keurig when the Keurig says descale the machine.

Here are the steps laid out on how to descale your Keurig and fix the Keurig descale light.

  1. Turn off your Keurig, be sure no power is in the machine.
  2. Empty the water filter inside the Keurig, and remove it.
  3. Pour the descale solution inside the machine to clean out any gunk.
  4. Switch your machine on, and put a cup underneath.
  5. Pour the mixture into a safe spot (sink)
  6. Switch on the brewer
  7. Rinse the water reservoir

Now, there you have it, how to properly fix your Keurig descale light! But that’s not all. You may still have the Keurig descale message, of your Keurig says descale still!

Keurig Duo Descale Light Stays On

This is another common problem; with a common fix, just clean your machine. Here is an in-depth guide on how to clean your Keurig Duo in just a few easy steps. Remember, if you clean your machine and the light stays on, all you have to do is hold down the 8oz and 10oz for 5 seconds and the light will turn off.

What If Descale Doesn’t Work?

If the Keurig descale does not work, and your light stays on, there is something wrong. The excess scale may have built up; to fix this, repeat the process with an extra solution. You can even descale your machine with something stronger like vinegar and let it sit for an hour or two. If you have a really annoying and strong build-up in your machine, citric acid will do the trick to pierce through it.

The Keurig descale light means something is blocking the water flow, so if it continues to stay on, you have to find out what is blocking the water flow through the machine, maybe a dodgy pipe or too a big a cup in your machine.

Cleaning The Keurig Exit Needle

Now, sometimes when you want to descale your Keurig and fix that descale light on your Keurig. Sometimes, you may need to clean the Keurig exit needle. If you look closely, you will notice a tiny bump that sticks out of the K-cup. What pierces the bump at the bottom of your cup is a little needle.

Sometimes, that needle can get blocked. This can happen from a build-up of ground coffee or just general gunk, and if this happens, you may not be able to brew any sort of coffee.

To fix this, just insert a sewing needle or paper clip and loosen the needle and clean it.

How Often Should I Descale My Keurig?

You should really be descaling your Keurig every three months, but that is just a guide. If you are using your Keurig way more than average, it may need to be done more often; it just depends.

Also, you have to make sure you are changing the water filter around every two months and cleaning it. Otherwise, your coffee can get a bad taste.
